You can also control the degree of the spline using the parameter degree, the default being cubic. You find then that > str(summary(reg)\$coef) ... > X <- summary(reg)\$coef > X[,2] (Intercept) x 0.03325738 0.05558073 gives you what you want. It checks for the kind of object that you are plotting and then calls the appropriate (more specialized) function to do the work. Standard Error Linear Regression If prediction is required for new data values then use the function predict.gamlss().

R uses + to combine elementary terms, as in A+B : for interactions, as in A:B; * for both main effects and interactions, so A*B = A+B+A:B A nice feature of However, summary seems to be the only way to manually access the standard error. I can't seem to figure it out. To change this use the option right=FALSE.

How do you solve the copied consciousness conundrum without killing anyone? You can get a bit more detail by requesting a summary: > summary(lmfit) Call: lm(formula = change ~ setting + effort) Residuals: Min 1Q Median 3Q Max -10.3475 -3.6426 0.6384 3.2250 If you like natural cubic splines, you can obtain a well-conditioned basis using the function ns, which has exactly the same arguments as bs except for degree, which is always three.
